SCOURING-MACHINE.

T 0 all whom it may concern:

Be it known that I, WILLAM 1.. Jacobs, a citizen of the United States ofAmerica, residing at Autreyville, in the county of Colqnitt and State ofGeorgia, have invented new and useful Improvements in Scouting-Machines,of which the following is a specification.

This invention relates to scouring machines and one, of the principalobjects of the same is to provide ellioient means for quickly scouringor scrubbing floors enibodying a rotary fountain brush connected to awater tank mounted on wheels and connected by a pipe to the brush and tobe pushed over the floor for scouring or scrubbing same.

Still another object of my invention is to provide means whereby therotary mop and the rotary scrubbing brush may be lowered relatively tothe wheels of the machine when said mop and scrubbing brush become worn.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawings, in which,

Figure l is a perspective view of a scrubbing machine made inaccordance-with my invention. Fig. 2 is a detail perspective view of themeans for adjusting the front axle vertically to compensate for the wearof the brushes. Fig. 3 is a detail section of the connection of thehollow pipe or shaft to which the rotary brush is attached.

Referring to the drawing for a more particular de scription of myinvention, the numeral 1 designates a water tank or reservoir which ismounted upon a frame 2 preferably composed of gas piping, as shown inthe drawing, and mounted upon wheels 3. A pipe 4 which communicates atits upper end with the tank 1, extends downward therefrom and outwardand is connected to a branch pipe 5. onnected to the branch pipe 5 is avertical pipe 6 to the lower end of which a scrubbing brush 7 isattached. Near the upper portion of the sec tion 6 of the pipe, abeveled gear wheel 8 is fixed which meshes with a larger beveled gear 9fixed to a shaft 10 mounted to rotate in bearings 11 on the frame, andsaid shaft having a grooved pulleyl2 thereon and a crank handle 13 atits outer end. A grooved pulley 14 on the rear axle 15 is connected tothe pulley 12 by means of a rope or cable 16, the purpose of which is torotate the shaft 10 when the machine is pushed over the floor. A globevalve 17 in the pipc 4 is used to regulate the flow of water throughsaid pipe to the scouring brush 7. The lower portion of the pipe 5 isprovided with a nipple l8 Specification of Letters Patent. Applicationfiled September 22. 1906- Serial No. 335,808;

l l l i I I l which rotates freely within the upper end 19 of the pipe Isection 6, as shown in Fig. 3. A mop or drying brush 20 is mounted upona rotary shaft 2], said shaft 21 being Patented Oct. 29, 1907.

connected to the elbow 22 in a manner similar to the connection of thepipe 6 with the branch pipe 5 and said shaft 2] being mounted in abearing 23 on theframe. Groove pulleys 24 and 25 on the pipe 6 and theshaft 21 are connected by a belt 26 in order that the scouring brush 7and the mop 20 will be simultaneously rotated. The front part of theframe is adjustably mounted on the front axle 15 by means of slottedbrackets 27, within which the axle rotates, so that as the mop and brushare worn away, the frame may be lowered slightly. The brackets 27, asshown in detail in Fig. 2, are each provided with a slot 28 throughwhich the axle 15 passes and at the upper end the bracket is bifurcated,as at 29, to embrace one of the corner posts of the frame 2. A lug 30provided with a threaded aperture is fitted with a set screw 31 whichbears at its lower-end upon'the axle 15" to hold said axle in adjustedposition.

The operation of my invention may be briefly described as follows: Aquantity of water having been placed in the tank 1 and the valve 17adjusted to regulate the flow of water required to the rotary brush 7,the machine is moved over the floor to be scoured and the crank 13 maybe operated to revolve the shaft 10,the pipe 6, and the brush 7. The mop20 is located im'mediately behind the brush 7 and is simultaneouslyrotated to wipe the floor by means of the belt 26. It will beunderstood, however, that the rope or cable 16 will rotate the brush 7and mop 20 without using the crank 13. When it is desired to adjust theframe to compen-- sate for wear of the brush and mop, the set screw 31is turned in order to slightly raise the front end of the frame.

From the foregoing it will be obvious that my invention is of a simplecharacter, can be manufactured at slight Cost, wil1qui ckly andefficiently scour a floor, and can be operated by an unskilled personwithout the expenditure of much power.

Having thus described the invention, what I claim is:

A machine of the character described comprising a water tank mountedupon a wheeled frame, a pipe leading from said tank and connected to abranch pipe provided with a nipple, a valve in said pipe for regulatingthe water flow, a vertical pipe section connected to a brush and theupper end thereof having the nipple seated therein, a shaft journaled inthe frame and provided with a beveled gear, a crank on said shaft and abeveled gear on the pipe section connected to the brush for rotatingsaid brush, substantially as'descrihed.

In testimony whereof, I affix of two witnesses.
